將字符串轉換日期的NSDate

Question

我想@"2016-04-15T15:00:00-07:00"轉換爲NSDate客觀C.我現在用的是NSdateFormatter@"yyyy-MM-dd'T'HH:mm:ssZZZZZ"，但沒有得到NSDate

我不得不作出從服務器字符串日期PST時間的NSDate

代碼：

NSString *strDate = @"2016-04-15T22:00:00Z"; 

NSDate* ts_utc; 

NSDateFormatter* df_utc = [[NSDateFormatter alloc] init]; 
[df_utc setTimeZone:[NSTimeZone timeZoneWithName:@"UTC"]]; 
[df_utc setDateFormat:@"yyyy-MM-dd'T'HH:mm:ssZZZZZ"]; 

ts_utc = [df_utc dateFromString:strDate]; 



NSDateFormatter* df_local = [[NSDateFormatter alloc] init]; 
[df_local setTimeZone:[NSTimeZone timeZoneWithName:@"PST"]]; 
[df_local setDateFormat:@"yyyy-MM-dd'T'HH:mm:ssZZZZZ"]; 

NSString* ts_local_string = [df_local stringFromDate:ts_utc]; 


NSDate *date = [df_local dateFromString:ts_local_string]; 

請建議。

我有同樣的問題，因爲你和我解決它以這種方式

NSString *strDate = @"2016-04-15T22:00:00Z"; 
NSDate* ts_utc; 
NSDateFormatter* df_utc = [[NSDateFormatter alloc] init]; 
[df_utc setTimeZone:[NSTimeZone timeZoneWithName:@"UTC"]]; 
[df_utc setDateFormat:@"yyyy-MM-dd'T'HH:mm:ssZZZZZ"]; 
ts_utc = [df_utc dateFromString:strDate]; 

NSTimeZone *destinationTimeZone = [NSTimeZone timeZoneWithName:@"PST"]; 
NSInteger timeZoneHourOffset = (NSInteger) ([destinationTimeZone secondsFromGMTForDate:ts_utc]/3600.0); //geting the time offset between UTC and PST 
NSDate *pstDate = [ts_utc dateByAddingTimeInterval:timeZoneHourOffset * 60 * 60]; //applying that offset into ts_utc NSDate 

希望，這將HEP你！
